Explanation: A metropolitan city is a large urban area that serves as a significant economic, cultural, and administrative center. The term "metropolitan" is often used to describe cities that have a high population density, a large number of residents, and a substantial impact on the region's economy and culture. In the context of India, metropolitan cities are often recognized for their role in national governance, economic activities, and cultural influence.
Delhi, the capital of India, is a prime example of a metropolitan city. It is not only the seat of the national government but also a major economic hub with a diverse range of industries, including finance, technology, and services. The city's population is over 20 million, making it one of the most populous urban areas in the world. This high population density, combined with its significant economic and administrative functions, qualifies Delhi as a metropolitan city.
Bangalore, while a large and economically significant city, is primarily known for its IT industry and is not classified as a metropolitan city in the context of this question. Similarly, Jaipur, the capital of Rajasthan, is a major city with historical and cultural significance but does not meet the specific criteria for being a metropolitan city. Indore, a significant city in Madhya Pradesh, is known for its industrial and commercial activities but does not have the same level of population density and administrative functions as a metropolitan city.
In summary, the classification of a city as metropolitan depends on its population density, economic activities, and administrative functions. Delhi, with its large population, significant economic role, and administrative importance, is correctly classified as a metropolitan city.
